BIRSS VRS 600 — R4 repair mix for high-strength concrete structures

Thixotropic repair mortars

Structures made of high-strength concrete are the speciality of BIRSS VRS 600: the thixotropic mix with fibre and compensated shrinkage restores their vertical and horizontal surfaces, corners of columns and beams and balcony edges destroyed by reinforcement corrosion, and fills non-moving working joints. It is not recommended as a pourable mortar. Class R4; compressive strength 25 MPa after one day and 60 MPa at 28 days, W18, F2 400, service temperature from −50 to +300 °C.
